The base station refers to a form of a radio station, which means that, in a certain radio coverage area, a control channel is sent to the terminal through the mobile communication switching center, so that the terminal determines the call information of the data channel according to the control channel. Radio access network equipment.

Thereby completing the communication function. The terminals mentioned in the embodiments of the present application are terminals of an unlicensed frequency band, and are referred to as terminals for convenience of description.

As shown in FIG. 1, the method includes:

101. The terminal acquires resource allocation information of a common control channel.

The common control channel refers to a control channel that the CE (coverage enhancement) user can use in common, and is used by the terminal to acquire control signaling to determine scheduling information of the data channel. The data channel is used to carry public broadcast data information or user-specific data information. That is, the common control channel implements coverage enhancement, and supports CSS (common search space) and USS (UE-specific search space).

The public broadcast data includes a paging message, system information (SI), or downlink transmission in a random access procedure (for example, RAR and Msg 4, Random access response, and Message 4).

It should be noted that the control signaling obtained through the common control channel includes, but is not limited to, scheduling information for determining a corresponding data channel, such as determining a transmission power or other information of the data channel.

The resource allocation information includes a set number of common control channels and/or a total frequency domain resource size of the common control channel and/or a frequency domain resource size of each common control channel set and a location of the common control channel in the frequency domain. And the start position of the common control channel in one transmission time interval and the position of the common control channel in the time domain.

The resource allocation information is used to indicate transmission of a common control channel. The resource allocation information may be acquired by the terminal through the base station, or may be acquired by the terminal through a predefined condition.

102. The terminal acquires a common control channel sent by the base station according to the resource allocation information.

103. The terminal determines scheduling information of a data channel according to the acquired common control channel.

After acquiring the common control channel sent by the base station according to the resource allocation information, the terminal performs combined decoding on the acquired common control channel to obtain scheduling information of the corresponding data channel.

It should be noted that, in order to perform coverage enhancement on the control channel of the CE user, the embodiment of the present application sends control signaling for data channel scheduling to the CE user through the common control channel. The common control channel is a common control channel introduced based on the original control channel of the CE user. The original control channel of the user may be a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (ePDCCH). The embodiment of the present application is based on the description of the ePDCCH, and the ePDCCH is used for coverage enhancement, and is used by the CE user to obtain control signaling. For differentiation, the coverage enhanced ePDCCH is named fePDCCH (further ePDCCH), and a common control channel is introduced on this basis, and is named as a common fePDCCH.

The embodiment of the present application provides a resource configuration method, for a non-authorized frequency band communication system, by using a resource configuration, a common control channel is introduced to determine scheduling information of a data channel, and the interaction between the base station and the terminal may be performed on a time-frequency basis. Repeated transmission of the common control channel enables coverage enhancement of the control channel in the unlicensed band communication system.

Further, in combination with the foregoing method flow, when the resource allocation information includes any one of a set number of common control channels, a total frequency domain resource size of a common control channel, and a frequency domain resource size of each common control channel set, When two pieces of information are used, the terminal calculates another unknown information among the three pieces of information according to two pieces of information known in the three pieces of information.

The terminal according to the total number of common control channels and the total frequency domain resource size of the common control channel and the frequency domain resource size of each common control channel set, and the common control channel in the frequency domain The location determines the frequency domain resources of the common control channel (transmission resources occupied throughout the system bandwidth). And, the terminal further determines a time domain resource (a transmission resource occupied in the time domain) of the common control channel according to a starting position of the common control channel in one transmission time interval and a position of the common control channel in the time domain.

Further, in combination with the foregoing method, the terminal may obtain the resource allocation information by using the broadcast information sent by the base station, and may obtain the resource allocation information according to the pre-defined conditions. Therefore, for the implementation of step 101, the implementation of the embodiment of the present application is Another possible implementation also provides the following method flow, including the following two implementation methods.

The first implementation, as shown in Figure 2, includes:

1011. The terminal acquires broadcast information sent by the base station, and determines resource allocation information of a common control channel by using the broadcast information.

The broadcast information is used to carry resource allocation information indicating a common control channel transmission.

The type of the broadcast information includes main information (MIB, Master Information Block) and/or system information (SIB1, System Information Block 1). The MIB is carried by a PBCH (physical broadcast channel) of the unlicensed band communication system. The MIB and the SIB1 are system information that the CE user can receive.

The second implementation, as shown in Figure 3, includes:

1012. The terminal acquires a predefined condition, and determines resource allocation information of a common control channel according to the predefined condition.

The predefined condition may be a fixed condition or a preset rule.

In order to explain more clearly the detailed process of the terminal acquiring the resource allocation information and other method flows that may be involved in the process of acquiring the resource allocation information, the following will separately acquire the number of sets of common control channels and the total frequency domain of the common control channel for the terminal. The size of the resource, the frequency domain resource size of each common control channel set, the location of the common control channel in the frequency domain, the starting position of the common control channel in one transmission time interval, and the location of the common control channel in the time domain Be explained.

First, the number of sets of common control channels:

The terminal may obtain the set number of the common control channel by using the broadcast information sent by the base station, and may also obtain the set number of the common control channel, such as a system, by using a pre-defined condition, as described in step 1011 and step 1012. The number of sets of fixed common control channels is 1.

Further, in combination with the foregoing method flow, the number of sets of the common control channel may be 1, or may be any natural number greater than 1 (for example, the number of sets of common control channels is 2). When the number of sets of the common control channel is greater than 1, another possible implementation manner of the embodiment of the present application provides the following two implementation manners for how to decode the set of common control channels, that is, according to the step 103 The process of determining the scheduling information of the data channel of the obtained common control channel includes the following two different method steps.

The first implementation, including:

1031. Jointly decode each common control channel set.

Step 1031 means that the terminal acquires the time-frequency resources of each common control channel set, and arranges them into a logical resource in a certain manner, and jointly decodes all the time-frequency resources on the logical resources.

As shown in FIG. 4, for a schematic diagram of jointly decoding each common control channel set, in FIG. 4, 201 and 202 represent frequency domain resources of the first common fePDCCH set, and 203 and 204 represent frequency of the second common fePDCCH set. Domain resource. After receiving all the time-frequency resources of the common fePDCCH, the user combines the logical resources of the common fePDCCH into small (eCCE#1, 2...N-1, N) indexes of eCCEs (enhanced control channel elements). To the large arrangement, then decode the control signaling #1, 2...K-1, K. Among them, N and K are natural numbers.

The second implementation includes:

1032. Independently decode each common control channel set.

Step 1032 refers to that the terminal acquires the time-frequency resources of each common control channel set, obtains the logical resources of each common control channel set in a certain manner, and independently decodes the public in each set on the logical resources corresponding to each set. Control channel.

As shown in FIG. 5, in order to independently decode a schematic diagram of each common control channel set, in FIG. 5, 301 and 302 represent frequency domain resources of the first common fePDCCH set, and 303 and 304 represent frequency of the second common fePDCCH set. Domain resource. After receiving the time-frequency resources of the two common fePDCCHs, the user constructs the logical resources 311 of the first common fePDCCH set and the logical resources 322 of the second common fePDCCH set, that is, the indexes of the eCCEs respectively (eCCE#1, 2... N-1, N, and eCCE#1, 2...M-1, M) are arranged from small to large, and then independently decode control signaling in each set (control signaling #1, 2...K-1, K, and control letter) Let #1, 2...L-1, L). Among them, N, M, K and L are natural numbers.

Second, the total frequency domain resource size of the common control channel:

As described in step 1011 and step 1012, the terminal may acquire the total frequency domain resource size of the common control channel by using the broadcast information sent by the base station; or obtain the total frequency of the common control channel by using a predefined condition. The size of the domain resource, for example, the total frequency domain resource size of the system default common control channel is 4 PRB (physical resource block) pairs, or 8 PRB pairs or 16 PRB pairs.

When the terminal obtains the total frequency domain resource size of the common control channel by using the broadcast information sent by the base station, the total frequency domain resource size of the common control channel may also be determined by an index method: for example, the broadcast information notifies the index of the resource size of the common control channel. . When the index is 0, it corresponds to 4 PRB pairs; when the index is 1, it corresponds to 8 PRB pairs; when the index is 2, it corresponds to 16 PRB pairs.

Third, the frequency domain resource size for each common control channel set:

As described in step 1011 and step 1012, the terminal may acquire the frequency domain resource size of each common control channel set by using the broadcast information sent by the base station; and each public control may also be obtained by using a predefined condition. The frequency domain resource size of the channel set, for example, the system defaults that the frequency domain resource size of each common control channel set is 8 PRB pairs.

Here, another unknown is calculated for how the terminal passes any two of the three information of the number of sets of the common control channel, the total frequency domain resource size of the common control channel, and the frequency domain resource size of each common control channel set. Information, for example.

For example, the number of sets of common control channels is 2, and the total frequency domain resource size of the common control channel is 16 PRB pairs. It can be seen that the frequency domain resource size of each common control channel set is 16/2=8 PRB pairs.

Example 2, giving the frequency domain resource size of each common control channel set, that is, enumerating the frequency domain resource sizes of the plurality of common control channel sets respectively. For example, given 4 and 8, respectively, that the frequency domain resource size of the first common control channel set is 4 PRB pairs, and the frequency domain resource size of the second common control channel set is 8 PRB pairs, it is known. The total frequency domain resource size of the common control channel is 4+8=12 PRB pairs.

Fourth, regarding the location of the common control channel in the frequency domain:

As described in step 1011, the terminal may acquire the location of the common control channel in the frequency domain by using broadcast information sent by the base station. It should be noted that when there are multiple common fePDCCH sets, each common fePDCCH set has corresponding independent resource allocation information or total joint resource allocation information in the frequency domain.

As described in step 1012, the terminal may also acquire the location of the common control channel in the frequency domain by using a pre-defined condition, that is, the terminal may determine the location of the common control channel in the frequency domain by using a preset rule. .

The terminal may have different preset rules for obtaining the preset control rule in the frequency domain by using a preset rule, but all include a cell ID and a downlink system frame. A function of some or all of the parameters. For example, the following three different preset rules are used to distinguish the first preset rule, the second preset rule, and the third preset rule.

First, an expression that gives three preset rules based on one common fePDCCH set.

(1) The first preset rule has the following expression:

表示小区cell ID；

表示下行系统带宽；M表示公共fePDCCH的资源大小，也即为PRB对的个数。 Where R _i represents an ith PRB pair in the common fePDCCH resource;

Indicates the cell cell ID;

Indicates the downlink system bandwidth; M indicates the resource size of the public fePDCCH, that is, the number of PRB pairs.

(2) The second preset rule has the following expression:

The parameter has the same meaning as the first preset rule.

(3) In order to implement the common fePDCCH, there are different transmission resources in different TTI (Transmission Time Interval). One TTI refers to the time interval occupied by the data channel once transmitted in the time domain. The frequency domain resource of the public fePDCCH can perform frequency hopping on the time domain, and the third preset rule has the following expression:

Where n _sf represents a TTI index; f _hop represents a frequency hopping interval in the time domain, which is also the number of PRB pairs. Other parameters have the same meaning as the first preset rule.

The f _hop can be configured by using broadcast information sent by the base station, for example, MIB or SIB1; the f _hop can also be determined by a predefined condition.

The n _sf may be a subframe index in a specific transmission period of the public fePDCCH. Includes a sub-frame index in a radio frame (value range can be 0-9); or a sub-frame index in a system frame period (value range can be 0-1023).

Secondly, when there are multiple common fePDCCH sets, the number of sets is N ^{common fePDCCH} , and the location of the common fePDCCH in the frequency domain can still be determined based on the above three preset rules. For convenience of description, the frequency domain resource occupied by the jth common fePDCCH set is denoted by S _j , and S ₀ represents the frequency domain resource occupied by the first common fePDCCH set.

S ₀ can be obtained by the first preset rule or the second preset rule or the third preset rule, and S ₀ is a set of R _i (i=0, 1, . . . , M−1). S _j can be calculated based on S ₀ , that is, a frequency domain offset is added to the frequency domain resource occupied by the first common fePDCCH set, and the frequency domain resources occupied by other common fePDCCH sets are obtained, and the following expression is specifically:

表示下行系统带宽。 Where f _shift represents a basic frequency domain offset;

Indicates the downlink system bandwidth.

The f _shift may be configured by using broadcast information sent by the base station, such as MIB or SIB1; the f _shift may also be determined by a predefined condition.

Fifth, regarding the starting position of the common control channel within a transmission time interval:

The terminal may obtain the starting position of the common control channel in a transmission time interval by using the broadcast information sent by the base station, as described in step 1011 and step 1012. The public control may also be obtained by using predefined conditions. The starting position of the channel within a transmission time interval.

即公共fePDCCH在一个TTI内的起始OFDM(Orthogonal frequency division multiplexing，正交频分复用)符号索引。当

为0，则表示公共fePDCCH是从一个TTI的第一个OFDM符号开始传输。 Wherein, the starting position of the public fePDCCH in one TTI is expressed as

That is, the common fePDCCH is an OFDM (Orthogonal Frequency Division Multiplexing) symbol index within one TTI. when

A value of 0 indicates that the common fePDCCH is transmitted from the first OFDM symbol of one TTI.

大于PDCCH的截止符号(截止OFDM符号)索引m，即至少满足

这里，一个系统中PDCCH的截止符号索引是通过CFI(control format indicator，控制格式指示值) 获得，即m＝CFI-1。因此，有

其中，CFI是通过PCFICH(physical control format indicator channel，物理控制格式指示信道)进行发送的。 among them,

The cutoff symbol (cutoff OFDM symbol) index m greater than the PDCCH, that is, at least

Here, the cutoff symbol index of the PDCCH in one system is obtained by CFI (control format indicator), that is, m=CFI-1. Therefore, there is

The CFI is transmitted through a PCFICH (physical control format indicator channel).

As shown in FIG. 5A, it is a schematic diagram of a relationship between PDCCH symbols occupied by a PDCCH and a common ePDCCH. c denotes a PDCCH, and a denotes a cutoff symbol index of the PDCCH. As shown in FIG. 5A, the PDCCH occupies the first three OFDM symbols of the first slot in the TTI, and the cutoff symbol is OFDM symbol #2. d denotes a common fePDCCH, and b denotes a start symbol (start OFDM symbol) index of the common fePDCCH. As shown in FIG. 5A, b is the OFDM symbol #3 of the first slot in the TTI.

获得CFI的取值。比如可以根据定义的关系式

解码CFI的取值。 Normally, CE users do not need to know the value of CFI. Considering that the CE user will jointly detect the PDCCH and the common fePDCCH to obtain control signaling, the CE user needs to know the CFI value. CE users do not decode PCFICH, but decode

Obtain the value of CFI. For example, according to the defined relationship

Decode the value of CFI.

的取值可以总是固定的，即

的取值是预先定义的，不需要信令进行设置。

的取值也可以是可变的。并且，在不同的数据传输情况下，

的取值有所不同。例如，当一个TTI中要发送系统的广播数据(例如，SI，Paging等)时，

的取值总是固定为2，即从第3个OFDM符号开始。当一个TTI中不包含所提的广播数据时，

的取值根据系统的信令配置信息而获取。其中，配置

的信令承载在MIB或SIB1里面。 among them,

The value can always be fixed, ie

The values are predefined and do not require signaling for setup.

The value can also be variable. And, in the case of different data transmissions,

The value is different. For example, when a system broadcast data (eg, SI, Paging, etc.) is to be sent in a TTI,

The value is always fixed at 2, that is, starting from the 3rd OFDM symbol. When a TTI does not contain the proposed broadcast data,

The value is obtained according to the signaling configuration information of the system. Among them, configuration

The signaling is carried in the MIB or SIB1.

Sixth, regarding the location of the common control channel in the time domain:

As described in step 1011 and step 1012, the terminal may acquire the location of the common control channel in the time domain by using the broadcast information sent by the base station; or acquire the common control channel at a pre-defined condition. The location on the domain.

In order to achieve coverage enhancement, the common fePDCCH needs to be repeatedly transmitted in the time domain, and each public fePDCCH transmission requires multiple TTIs.

The starting position of a common fePDCCH in the time domain may be any TTI, that is, one common fePDCCH may be sent in each TTI; or may be a specified TTI, that is, a starting position of a common fePDCCH in the time domain. Limited by certain TTIs.

The specified TTI may be a TTI whose index is a multiple of a common fePDCCH duration.

The common fePDCCH duration refers to the number of TTIs required for a common fePDCCH to be completely transmitted in the time domain.

As shown in FIG. 6, the starting position of the public fePDCCH in the time domain is an arbitrary TTI. As shown in FIG. 6, the transmission of one common fePDCCH requires N TTIs. 430 and 440 respectively represent two common fePDCCHs that are independently transmitted in the time domain, starting at TTI 401 and TTI 402 respectively, that is, one common fePDCCH may start at any one TTI.

As shown in FIG. 7, the starting position of the common fePDCCH in the time domain is a schematic diagram of the index being a common fePDCCH duration multiple TTI. As shown in FIG. 7, the transmission of one common fePDCCH requires N TTIs. 530 and 540 respectively represent two common fePDCCHs that are independently transmitted in the time domain, starting at TTI 501 and TTI 511, respectively, and 501 and 511 are multiples of N.
